Cheating Policy

Email (use your uni)

I receive emails at both and

For official correspondence concerning this course, you must include your uni. The easiest way to do this is to send emails from your email address based on your uni. When I search for emails from students, I search by uni, and only by uni. If your email does not include your uni, it is as if you never sent it.

I am aware that Columbia provides some students with “vanity” email addresses of the form These are a poor idea. If you use such an address, you will sometimes forget to include your uni.

Homework, and Preparation for Exams

These study guides describe the chapters of Bretscher to study for our exams, topics to learn, a list of homework exercises to be graded, and many practice exam problems from past years.

I have posted first and second exams and solutions to our Linear Algebra Course Materials page.

Graded exams and grade reports have been returned as PDF files to your CourseWorks Dropbox.


These are videos of the 8:40am-9:55am lectures.
